Set Storage Accelerator and Space Reclamation Blackout Times for View Composer Linked Clones

<

For View Composer linked clones, regenerating digest files for View Storage Accelerator and reclaiming virtual machine disk space can use ESXi resources. To ensure that ESXi resources are dedicated to foreground tasks when necessary, you can prevent the ESXi hosts from performing these operations during specified periods of time on specified days.

About this task

Note:

For instant clones, this feature is not needed.

For example, you can specify a blackout period during weekday morning hours when users start work, and boot storms and anti-virus scanning I/O storms take place. You can specify different blackout times on different days.

Disk space reclamation and View Storage Accelerator digest file regeneration do not occur during blackout times that you set. You cannot set separate blackout times for each operation.

View allows View Storage Accelerator digest files to be created for new machines during the provisioning stage, even when a blackout time is in effect.

The following procedure applies to linked-clone desktop pools. The steps are similar for automated farms.

Prerequisites

Verify that Enable View Storage Accelerator, Enable space reclamation, or both features are selected for vCenter Server.

Verify that Use View Storage Accelerator, Reclaim VM disk space, or both features are selected for the desktop pool.

Procedure

On the Advanced Storage page in the Add Desktop Pool wizard, go to Blackout Times and click Add.

If you are editing an existing pool, click the Advanced Storage tab.

Check the blackout days and specify the starting and ending times.

The time selector uses a 24-hour clock. For example, 10:00 is 10:00 a.m., and 22:00 is 10:00 p.m.

Click OK.

To add another blackout period, click Add and specify another period.

To modify or remove a blackout period, select the period from the Blackout times list and click Edit or Remove.
